Disassembly of the remote control and replacement of the battery for the Mercedes C-Class.

Model: Mercedes Classe C W203 - Years 2000-2007
Part: Key

Today's guide will show us how to disassemble the remote control and replace the battery of the Mercedes C-Class key. First, we take our remote control and start removing the battery tray, pulling it towards the back of the remote control; this way we can remove and replace the old battery with the new one (of the correct type and with the same code), as shown in the video. At this point, we pry open the slot of the remote control if we want to open it and possibly replace the key shell; all that's left to do is reassemble everything!
